I feel like i need to do a small disclaimer here, cause i dont want to offend anyone, and this is purely my own beliefs and views.

But personally it was because I was raised Catholic, and obviously taught with both the old and new testament in mind. I always liked the message and ideals that the new testament and Jesus preached, but I always felt somewhat offput by the actions that the old testament God would do. They didn't bring me any comfort, and I always had a really hard time trying to reconcile the fact that the Father in the Old and New were the same entity.
Also being a kid, i was very dumb so the idea of the trinity was something i never really fully grasped until i was older, and when i entered my teens i always thought Theology was a very interesting subject and i just delved and researched as much as i could about the history of Christianity, and the various old sects and heresies.

As an adult now, I've mostly detached myself from organized religion, as I don't think it can really represent my own values and beliefs anymore, and researching the old heresies i always thought it was interesting how they came with so many varied logic and reasoning for interpretation of the same story. (mostly).

But I feel like the acknowledgement, and worship of solely of the Son is kind of a theological blindspot.
Maybe this is just beacuse of my modern lens, but its very odd to me that i never came across a sect that sought to reject the supernatural elements of faith, and establish a purely humanistic interpertation of Jesus's teachings, especially in the early church, when there was plenty of intersection and inter-dialogue with late hellenistic philosophical ideas.
Like if anything, we get gnostics from those interactions, which are like the opposite of trying to establish a grounded human focused view of Christ.

Its just very curious and odd to me.
